It is designed to heat water by burning wood, making it suitable for outdoor hot tubs and baths. The outer diameter is 1″ with a 3/4″ male NPT connector, and the total coil length is 29 feet. The product is customizable in dimension and water connector to meet unique installation requirements.
QUELECO Custom Made 304 Stainless Steel Coil
This custom coil is also constructed from food-grade 304 stainless steel and designed for heat exchange and cooling across pools, heat pumps, or water chillers. It features a 1.5″ outer diameter pipe with a 0.05″ wall and a 3/4″ NPT connection. The total length spans approximately 59 feet with 13.5 turns, and the design emphasizes durability and corrosion resistance for long-term operation.
Vigorous Wort Chiller: Stainless Coil For Brewing
The Vigorous wort chiller uses a 3/4″ diameter stainless steel coil with 25 feet of length. It is designed to chill wort efficiently and is built to meet ASTM A269 standards, ensuring reliable performance in brewing setups. Its corrosion resistance and straightforward installation make it a common choice for home and small-scale breweries.
NY Brew Supply 1/2″ Stainless Steel Coil (50′)
This 1/2″ stainless steel coil runs 50 feet in length with a compact overall footprint, suitable for compact heat exchange installations. It uses standard 1/2″ tubing and is noted for straightforward handling and durable construction. The coil is ideal for applications requiring a compact, efficient heat transfer solution.
AB Pool Heat Exchanger 316L
Designed for pool and spa heating, this exchanger uses 316L stainless steel for enhanced corrosion resistance in chemical-treated water. It delivers up to 155 kBtu/hr of heating capacity and includes long-term warranty coverage. Its robust construction makes it suitable for larger residential and commercial pools.
AB 25″ Side Arm Heat Exchanger
This 25″ side-arm heat exchanger features a finned stainless steel interior to boost heat transfer while maintaining relatively low pressure drop. It handles up to 13,500 Btu/hr and uses 3/4″ FNPT connections on the tank side and 1″ FNPT on the heater side. The design supports quick, efficient heating for larger tanks and systems.
ALECOIL Plate Heat Exchanger (316L)
ALECOIL’s plate heat exchanger uses 316L stainless steel with a brazed copper assembly for high strength and wide compatibility with high-temperature and high-pressure systems. The asymmetric fishbone plate design promotes strong turbulence and high heat transfer rates, while reducing secondary-side pressure drop. It’s a robust choice for efficient water heating and industrial applications.
NY Brew Supply 1/2″ x 50′ Wort Chiller Coil
This half-inch stainless steel wort chiller coil spans 50 feet with brass garden hose fittings, suitable for brewing setups that require a compact but high-capacity cooling solution. The coil is designed for easy installation and reliable performance in cold-water transfer tasks.
Buying Guide: Choosing The Right Stainless Steel Coil Heat Exchanger
Purpose and compatibility: Identify whether you need heating, cooling, or both, and ensure the exchanger materials and ports (1/2″, 3/4″, or 1″ FNPT) match your system. Consider whether the unit will be used with wood-fire heating, gas, or electric sources, and check for stainless steel grades (304 vs 316L) to match chemical exposure and corrosion resistance.
Size and capacity: Coil length, diameter, wall thickness, and the number of turns affect heat transfer efficiency and flow resistance. Larger coils provide more surface area but require more pump power. Review manufacturers’ specifications (BTU/hr or kW) relative to your desired output.
Durability and maintenance: Look for food-grade or medical-grade stainless steel for longer service life and ease of cleaning. Anti-corrosion properties are essential in water-rich environments, especially where chlorine or minerals are present.
Customization options: Some products offer customizable dimensions, connectors, and capacities. If you have unique installation constraints, prioritize manufacturers that support tailored solutions and quick delivery.
Installation and compatibility: Ensure the coil’s connector type and thread size align with your plumbing or heating equipment. Check compatibility with pool, spa, or industrial systems to avoid pressure or flow mismatches.
Warranty and support: A solid warranty helps protect your investment against manufacturing defects and wear. Look for brands offering technical support and documented performance data to assist with setup and optimization.
Cost vs. efficiency: While price matters, prioritize overall system efficiency and long-term operating costs. A higher-efficiency exchanger with lower energy or pumping requirements often saves money over time, even if upfront costs are higher.
Regulatory and safety considerations: For food-grade or brewing applications, verify that the coil meets applicable standards (such as ASTM), and ensure proper sanitation and cleaning procedures are feasible in your use case.
